Female USB connector 11 is coilfigured to mate with a male USB connector of another flash memory drive. This other flash meinory drive can either be a prior art flash memory drive or a flash memory drive in accordance with the present invention.
[0024] One or more flash memory chips 13, a download/copy logic chip 15, a hub logic chip 17 and a battery 19 can be mounted on printed circuit board 7 in a manner known in the art. Hereafter, it will be assumed that only one flash memory chip 13 is present. However, this is not to be construed as limiting the invention. Flash memory chip 13 is configured to store anywhere from 8 megabytes to 1 gigabyte of data.
Download/copy logic chip 15, which is electrically connected to flash memory chip 13, facilitates the transfer of data stored therein to a flash memory chip of another flash memory drive, or vice versa. Hub logic chip 17 facilitates connection of one or both of male USB connector 10 and female USB connector 11 to a universal serial bus having connected thereto one or more other devices, such as, without limitation, a prior art flash memory drive, anotlier flash memory drive in accordance with the present invention, a desktop computer, a laptop computer, a palm device, a printer, a digital camera, a scanner, and the like. Battery 19 provides power to flash memory chip 13, download/copy logic chip 15 and hub logic chip 17 when flash memory drive 1 is not attached to the USB port of an externally powered device, such as a computer, palm device, etc. Battery 19 enables the combination of flash memory chip 13, download/copy logic chip 15 and hub logic chip 17 to transfer data from flash memory chip 13 to the flash memory chip of another flash memory drive, or vice versa, attached to male USB connector 9 or female USB connector 11 without the use of such an externally powered device. A logic chip (not shown) can be electrically coupled to battery 19 to enable the charging of battery 19 when male USB
connector 9 or female USB connector 11 of flash meinory drive 1 is connected to an externally powered device. While battery 19 is used in the present embodiment, it is envisioned that flash memory drive 1 may also or alternatively include other power supplies, such as one or more solar cells that can be utilized to power chips 13, 15 and 17 and/or charge battery 19. While download/copy logic chip 15, hub logic chip 17 and the logic chip for enabling the battery to charge are described above as separate chips, it is envisioned that that the function of each of these chips could be incorporated into one or two cliips. Accordingly, the number of chips described herein is not to be construed as limiting the invention.
Download/copy logic chip 15, which is electrically connected to flash memory chip 13, facilitates the transfer of data stored therein to a flash memory chip of another flash memory drive, or vice versa. Hub logic chip 17 facilitates connection of one or both of male USB connector 10 and female USB connector 11 to a universal serial bus having connected thereto one or more other devices, such as, without limitation, a prior art flash memory drive, anotlier flash memory drive in accordance with the present invention, a desktop computer, a laptop computer, a palm device, a printer, a digital camera, a scanner, and the like. Battery 19 provides power to flash memory chip 13, download/copy logic chip 15 and hub logic chip 17 when flash memory drive 1 is not attached to the USB port of an externally powered device, such as a computer, palm device, etc. Battery 19 enables the combination of flash memory chip 13, download/copy logic chip 15 and hub logic chip 17 to transfer data from flash memory chip 13 to the flash memory chip of another flash memory drive, or vice versa, attached to male USB connector 9 or female USB connector 11 without the use of such an externally powered device. A logic chip (not shown) can be electrically coupled to battery 19 to enable the charging of battery 19 when male USB
connector 9 or female USB connector 11 of flash meinory drive 1 is connected to an externally powered device. While battery 19 is used in the present embodiment, it is envisioned that flash memory drive 1 may also or alternatively include other power supplies, such as one or more solar cells that can be utilized to power chips 13, 15 and 17 and/or charge battery 19. While download/copy logic chip 15, hub logic chip 17 and the logic chip for enabling the battery to charge are described above as separate chips, it is envisioned that that the function of each of these chips could be incorporated into one or two cliips. Accordingly, the number of chips described herein is not to be construed as limiting the invention.
[0025] With reference to Fig. 3 and with continuing reference to Figs. 1 and 2, a first flash memory drive 1 a and a second flash memory drive 1 b, both in accordance with the present invention, can be joined togetlier by inserting fihe male USB
connector 9a of first flash memory drive 1a to the female USB connector 11b of a second flash memory drive lb for the purpose of transferring or copying data from the flash memory chip of first flash memory drive 1 a to the flash memory chip of second flash memory drive lb, or vice versa.
connector 9a of first flash memory drive 1a to the female USB connector 11b of a second flash memory drive lb for the purpose of transferring or copying data from the flash memory chip of first flash memory drive 1 a to the flash memory chip of second flash memory drive lb, or vice versa.
[0026] Each flash memory drive 1 can include a master/slave switch 21 coupled to download/copy logic chip 15 for setting the flash memory drive as either a master or a slave. In operation, when first flash memory drive 1 a and second flash memory drive lb are joined together, the flash memory drive set to be the master transfers data from its flash memory chip to the flash memory chip of the flash memory drive set to be the slave. For example, first flash memory drive la can be set as the master and second flash memory drive lb can be set as the slave using each flash memory drive's master/slave switch 21. Hence, when first flash memory drive 1 a and second flash memory drive Ib are joined together data is transferred from the flash memory chip of first flash memory drive 1 a to the flash memory chip of second flash memory drive lb.
[0027] When flash memory drive 1 in accordance with the present invention is utilized with a conventional, prior art flash memory drive having only a male USB
connector, the master/slave switch 21 of flash memory drive 1 can set flash memory drive 1 as the master for transferring data from the flash memory chip of flash memory drive 1 to the flash memory chip of the prior art flash memory drive.
Alternatively, the master/slave switch 21 of flash memory drive 1 in accordance with the present invention can set flash memory drive 1 as the slave for transferring data from the flash memory chip of the prior art flash memory drive to the flash memory chip 13 of flash memory drive 1 in accordance with the present invention.
Thus, it can be seen that flash memory drive 1 in accordance with the present invention can be used with other flash memory drives 1 in accordance with the present invention or with prior art flash memory drives.
[00281 Desirably, when male USB connector 9 is plugged into a female USB
connector of a computer, a palm device, and the like, the transfer of data to or from flash memory chip 13 can be controlled via the device in a manner known in the art.
Thus, desirably, it is only when the master/slave switch 21 sets flash memory drive 1 as the master that flash memory drive 1 is operative for controlling the transfer of data from its flash memory chip 13. This is in contrast to when master/slave switch 21 sets flash memory drive 1 as a slave, wherein flash memory drive 1 enables data to be transferred into its flash memory chip 13 under the control of another flash memory drive in accordance with the present invention, from a prior art flash memory drive or under the control of a computer, palm device, and the like.
[0029] A push button switch 23 can be provided on printed circuit board 7 and accessible via top cover 3 to allow for manual activation of the transfer of data between coupled flash memory drives. For example, in response to activation of push button switch 23 of first flash memory drive 1 a, set as a master by master/slave switch 21, download/copy logic chip 15 of first flash memory drive la transfers data from the flash memory chip 13 of flash memory drive 1 a to the flash memory chip 13 of either second flash memory drive lb or a prior art flash memory drive (not shown) coupled to first flash meinory drive 1 a. However, the use of push button switch 23 is not to be construed as limiting the invention since it is envisioned that other control means can be utilized to cause the transfer of data between flash memory drives. For example, flash memory drive 1 can be responsive to the setting of master/slave switch 21 for transferring data to or from its flash memory chip when flash memory drive 1 is connected to another flash memory drive in accordance with the present invention or a prior art flash memory drive.
[0030] Each flash memory drive 1 can also include a plurality of light emitting diodes (LEDs) 25a, 25b and 25c. LEDs 25a, 25b and 25c provide the user with an indication of the status of flash memory drive 1. For instance, LED 25a illuminates when flash memory drive 1 is on. LED 25a also provides a blinking illumination when data is being transferred therefrom to either another flash memory drive in accordance with the present invention or a prior art flash memory drive, or vice versa.
LED 25a then returns to a steady illumination indicating that the data transfer is complete. LED 25b is illuininated only in the occurrence of an error in flash memory drive 1. Finally, LED 25c provides an indication of the status of battery 19 of flash memory device 1. If LED 25c is providing a steady illumination, battery 19 is charging. LED 25c provides a blinking illumination when battery 19 has a low charge. LEDs 25a, 25b and 25c may be selected from any light emitting device suitable for such an application and may be any color. LEDs 25a, 25b and 25c are desirably each a different color.
[0031] Flash memory drive 1 may fiu-ther include a reset button (not shown).
The reset button allows a user to restart flash memory drive 1 if LED 25b is illuminated indicating that an error has occurred in flash memory drive 1. Once the reset button is pressed, flash memory drive 1 is powered down and may then be restarted.
[0032] With reference to Fig. 4 and with continuing reference to Figs. 1 and 2, flash memory drive 1 may also be used to maximize the available USB ports on a computer or palm device. Specifically, male USB connector 9 of flash memory drive 1 may be inserted into a USB port of a computer (not shown). Thereafter, female USB
connector 11 can accept a male USB connector 27 of a USB cable. This enables peripheral devices, such as cameras, printers, scanners or additional flash memory drives, to utilize the same USB port on a computer as flash memory drive 1.
[0033] With reference to Figs. 5a and 5b, a second embodiment of flash memory drive 1 includes a digital audio chip 29 and an output connector 31, such as a headphone jack. Digital audio chip 29 includes a digital signal processor (DSP), an amplifier and a digital-to-analog converter (DAC). The DSP can retrieve digital audio data from flash memory chip 13 and can decode said digital audio data utilizing a decompression algorithm, such as an mp3 or wma decompression algorithm, that undoes the compression of the digital audio data stored in a corresponding compressed format on flash memory chip 13. Then, the DAC converts the decompressed audio data back into an analog audio data. Finally, the amplifier boosts the strength of the signal and sends it to sound output connector 31. Buttons 33 can be provided on top cover 3 for controlling digital audio chip 29. Buttons 33 peirform such functions as playing the digital audio data, stopping, pausing, skipping, rewinding and the like. While push button switch 23 is shown, the function provided by push button switch 23 can be incorporated into one or more buttons 33, whereupon push button switch 23 can be omitted from the embodiment shown in Figs. 5a and 5b.
[0034] With reference to Fig. 6, a third embodiment a flash memory drive 1 includes a display screen 35 viewable via top cover 3. Display screen 35 can be connected to suitable circuitry mounted on printed circuit board 7 for providing a visual indication of the title of the digital audio data, the time remaining in a song and other useful and desirable information. This elnbodiment can replace push button 23 a.nd/or master/slave switch 21 witli buttons 33. Flash memory drive 1 can be programmed so download/copy logic chip 15 is responsive to the actuation of one or more buttons 33 for setting the device to be a master or a slave. A visual indication of "Master" or "Slave" can be provided on display screen 33. A signal can also be sent to download/copy logic chip 15 to initiate the transfer of data to or from flash memory clup 13 when another one of the buttons 33 is pressed. A visual indication such as "Transfer in Progress" may be provided on display screen 35, thereby obviating the need for LEDs 25a, 25b and 25c. However, display screen 35 and LEDs 25a, 25b and 25c may also be used together in a single embodiment. Display screen 35 can be a liquid crystal display (LCD), a plasma screen or the like.
[0035] With reference to Fig. 7, the present invention is also a method for transferring data to or from the flash memory chip of a flash memory drive with integrated male and female connectors. The method begins at step 61 by inserting the male connector of a first flash memory drive into the female comiector of a second flash memory drive. Next, at step 63, the first drive is set to master and the second drive is set to slave using each of the drive's master/slave switches. Then, at step 65, the push button switch is activated to initiate the transfer of data from the flash memory chip of the first flash memory drive to the flash memory chip of the second flash memory drive. Finally, at step 67, the data is transferred from the flash memory chip of the first drive to the flash memory chip of the second drive. The preceding method is illustrative of the transfer of data between two flash memory drives in accordance with the present invention and is not to be construed as limiting the invention. The transfer of data between a flash memory drive in accordance with the present invention and prior art flash memory drives, computers, palm devices, laptops, and the like is also envisioned. For example, when the male connector of a prior art flash memory drive is inserted into the female connector of a flash memory drive in accordance with the present invention, the master/slave switch of the flash memory drive in accordance with the present invention is set to master for transferring data from the flash memory chip of flash memory drive in accordance with the present invention to the flash memory chip of the prior art flash memory drive. A further example is wlien the male connector of a flash memory drive in accordance with the present invention is inserted into the female connector of a computer, palm device and the like, the transfer of data to or from the flash memory chip of the flash memory drive in accordance with the present invention can be controlled by the computer, palm device and the like in a manner known in the art.
[00361 VJhile the present invention was described with reference to preferred embodiments of the flash memory drive with integrated male and female connectors, those skilled in the art may make modifications and alterations to the present invention without departing from the scope and spirit of the invention.
Accordingly, the above detailed description is intended to be illustrative rather than restrictive. The invention is defined by the appended claims, and all changes to the invention that fall within the meaning and range of equivalency of the claims are to be embraced by their scope.
connector, the master/slave switch 21 of flash memory drive 1 can set flash memory drive 1 as the master for transferring data from the flash memory chip of flash memory drive 1 to the flash memory chip of the prior art flash memory drive.
Alternatively, the master/slave switch 21 of flash memory drive 1 in accordance with the present invention can set flash memory drive 1 as the slave for transferring data from the flash memory chip of the prior art flash memory drive to the flash memory chip 13 of flash memory drive 1 in accordance with the present invention.
Thus, it can be seen that flash memory drive 1 in accordance with the present invention can be used with other flash memory drives 1 in accordance with the present invention or with prior art flash memory drives.
[00281 Desirably, when male USB connector 9 is plugged into a female USB
connector of a computer, a palm device, and the like, the transfer of data to or from flash memory chip 13 can be controlled via the device in a manner known in the art.
Thus, desirably, it is only when the master/slave switch 21 sets flash memory drive 1 as the master that flash memory drive 1 is operative for controlling the transfer of data from its flash memory chip 13. This is in contrast to when master/slave switch 21 sets flash memory drive 1 as a slave, wherein flash memory drive 1 enables data to be transferred into its flash memory chip 13 under the control of another flash memory drive in accordance with the present invention, from a prior art flash memory drive or under the control of a computer, palm device, and the like.
[0029] A push button switch 23 can be provided on printed circuit board 7 and accessible via top cover 3 to allow for manual activation of the transfer of data between coupled flash memory drives. For example, in response to activation of push button switch 23 of first flash memory drive 1 a, set as a master by master/slave switch 21, download/copy logic chip 15 of first flash memory drive la transfers data from the flash memory chip 13 of flash memory drive 1 a to the flash memory chip 13 of either second flash memory drive lb or a prior art flash memory drive (not shown) coupled to first flash meinory drive 1 a. However, the use of push button switch 23 is not to be construed as limiting the invention since it is envisioned that other control means can be utilized to cause the transfer of data between flash memory drives. For example, flash memory drive 1 can be responsive to the setting of master/slave switch 21 for transferring data to or from its flash memory chip when flash memory drive 1 is connected to another flash memory drive in accordance with the present invention or a prior art flash memory drive.
[0030] Each flash memory drive 1 can also include a plurality of light emitting diodes (LEDs) 25a, 25b and 25c. LEDs 25a, 25b and 25c provide the user with an indication of the status of flash memory drive 1. For instance, LED 25a illuminates when flash memory drive 1 is on. LED 25a also provides a blinking illumination when data is being transferred therefrom to either another flash memory drive in accordance with the present invention or a prior art flash memory drive, or vice versa.
LED 25a then returns to a steady illumination indicating that the data transfer is complete. LED 25b is illuininated only in the occurrence of an error in flash memory drive 1. Finally, LED 25c provides an indication of the status of battery 19 of flash memory device 1. If LED 25c is providing a steady illumination, battery 19 is charging. LED 25c provides a blinking illumination when battery 19 has a low charge. LEDs 25a, 25b and 25c may be selected from any light emitting device suitable for such an application and may be any color. LEDs 25a, 25b and 25c are desirably each a different color.
[0031] Flash memory drive 1 may fiu-ther include a reset button (not shown).
The reset button allows a user to restart flash memory drive 1 if LED 25b is illuminated indicating that an error has occurred in flash memory drive 1. Once the reset button is pressed, flash memory drive 1 is powered down and may then be restarted.
[0032] With reference to Fig. 4 and with continuing reference to Figs. 1 and 2, flash memory drive 1 may also be used to maximize the available USB ports on a computer or palm device. Specifically, male USB connector 9 of flash memory drive 1 may be inserted into a USB port of a computer (not shown). Thereafter, female USB
connector 11 can accept a male USB connector 27 of a USB cable. This enables peripheral devices, such as cameras, printers, scanners or additional flash memory drives, to utilize the same USB port on a computer as flash memory drive 1.
[0033] With reference to Figs. 5a and 5b, a second embodiment of flash memory drive 1 includes a digital audio chip 29 and an output connector 31, such as a headphone jack. Digital audio chip 29 includes a digital signal processor (DSP), an amplifier and a digital-to-analog converter (DAC). The DSP can retrieve digital audio data from flash memory chip 13 and can decode said digital audio data utilizing a decompression algorithm, such as an mp3 or wma decompression algorithm, that undoes the compression of the digital audio data stored in a corresponding compressed format on flash memory chip 13. Then, the DAC converts the decompressed audio data back into an analog audio data. Finally, the amplifier boosts the strength of the signal and sends it to sound output connector 31. Buttons 33 can be provided on top cover 3 for controlling digital audio chip 29. Buttons 33 peirform such functions as playing the digital audio data, stopping, pausing, skipping, rewinding and the like. While push button switch 23 is shown, the function provided by push button switch 23 can be incorporated into one or more buttons 33, whereupon push button switch 23 can be omitted from the embodiment shown in Figs. 5a and 5b.
[0034] With reference to Fig. 6, a third embodiment a flash memory drive 1 includes a display screen 35 viewable via top cover 3. Display screen 35 can be connected to suitable circuitry mounted on printed circuit board 7 for providing a visual indication of the title of the digital audio data, the time remaining in a song and other useful and desirable information. This elnbodiment can replace push button 23 a.nd/or master/slave switch 21 witli buttons 33. Flash memory drive 1 can be programmed so download/copy logic chip 15 is responsive to the actuation of one or more buttons 33 for setting the device to be a master or a slave. A visual indication of "Master" or "Slave" can be provided on display screen 33. A signal can also be sent to download/copy logic chip 15 to initiate the transfer of data to or from flash memory clup 13 when another one of the buttons 33 is pressed. A visual indication such as "Transfer in Progress" may be provided on display screen 35, thereby obviating the need for LEDs 25a, 25b and 25c. However, display screen 35 and LEDs 25a, 25b and 25c may also be used together in a single embodiment. Display screen 35 can be a liquid crystal display (LCD), a plasma screen or the like.
[0035] With reference to Fig. 7, the present invention is also a method for transferring data to or from the flash memory chip of a flash memory drive with integrated male and female connectors. The method begins at step 61 by inserting the male connector of a first flash memory drive into the female comiector of a second flash memory drive. Next, at step 63, the first drive is set to master and the second drive is set to slave using each of the drive's master/slave switches. Then, at step 65, the push button switch is activated to initiate the transfer of data from the flash memory chip of the first flash memory drive to the flash memory chip of the second flash memory drive. Finally, at step 67, the data is transferred from the flash memory chip of the first drive to the flash memory chip of the second drive. The preceding method is illustrative of the transfer of data between two flash memory drives in accordance with the present invention and is not to be construed as limiting the invention. The transfer of data between a flash memory drive in accordance with the present invention and prior art flash memory drives, computers, palm devices, laptops, and the like is also envisioned. For example, when the male connector of a prior art flash memory drive is inserted into the female connector of a flash memory drive in accordance with the present invention, the master/slave switch of the flash memory drive in accordance with the present invention is set to master for transferring data from the flash memory chip of flash memory drive in accordance with the present invention to the flash memory chip of the prior art flash memory drive. A further example is wlien the male connector of a flash memory drive in accordance with the present invention is inserted into the female connector of a computer, palm device and the like, the transfer of data to or from the flash memory chip of the flash memory drive in accordance with the present invention can be controlled by the computer, palm device and the like in a manner known in the art.
[00361 VJhile the present invention was described with reference to preferred embodiments of the flash memory drive with integrated male and female connectors, those skilled in the art may make modifications and alterations to the present invention without departing from the scope and spirit of the invention.
Accordingly, the above detailed description is intended to be illustrative rather than restrictive. The invention is defined by the appended claims, and all changes to the invention that fall within the meaning and range of equivalency of the claims are to be embraced by their scope.
